WINDOW-SHADE FIXTURE.

Application filed June 18, 1923. Serial No. 646,149.

To all whom it may concern:

Be it known that ALVA BERNARD SMITH, late a citizen of the United. States, and formerly residing in the city of St. Louis, State of Missouri, did prior to his decease invent a certain new and useful Improvement in lVindow-Shade Fixtures, of which the following is a specification, reference being had to the accompanying drawings, formingla part thereof.

This invention relates to a certain new and useful improvement in window-shade fixtures.

The invention has for its chief object the provision of a window-shade fixture of the adjustable or shiftable type for locating the shade-roller and its attached shade at selective altitudes upon and relative to the window, which is simple, inexpensive, and durable in form and construction, readily and conveniently installed, and easily and efliciently operable.

\Vith the above and other objects in view, the present invention resides in the novel features of form, construction, arrangement, and combination of parts hereinafter described and afterwards pointed out in the claims. I

In the accompanying drawings,

Figure 1 shows fragmentarily an inside view of a window-frame equipped with a shade-fixture embodyingthe present invention, as installed between the jambs;

Figure 2 isa View similar to Figured showing the fixture asinstalled on the face ofthe frame; v Figure 3 is an enlarged elevation, partly broken away, of the fixture of Figure 2, Figures 4 and 5 are sectional plan views taken, respectively, on the lines 44 and 5-5, Figure 1, showing the arrangement of pulleys for the installation there illustrated; Figure 6 is a sectional plan view'on approximately the line 6+6, FigureB, showing the track and runner of Figure 2 and a separate roller bracket; 7

Figures 7 and Sam enlarged detail sectional views similar to Figures 4 and 5 taken, respectively, on the lines 7-7 and S-8, Figure 3, showing the arrangement of pulleys for the installation shown in Figure 2;

Figure 9 1s a diagrammatic View, showing the arrangement of pulleys and cord for the downward movement or shifting of the roller-brackets or runners;

Figure 10 is'a view similar to Figure 9, showing the arrangement of the pulleys and cord for the upward movement or shifting of the roller-brackets or runners;

Figure 11 is a view similar to Figures 9 and 10, showing the arrangement of the pulleys and cord which tensionally maintain the roller-brackets or runners and ,theirsupported roller and shade in shifted or adjusted positions;

Figure 12 1s a perspective View of'the runner adapted to receive the spring'con-c trolling support of the shade-roller; and

Figure 13 is a perspective View of the runner adapted to receive the rotatable support of the shade-roller.

Referring now more indetail and by reference characters to the said drawings, which illustrate a preferred embodiment of the invention, 1 and 2 designate tracks or rails, which are substantially identical-in form and construction and preferably of channel section, and which are provided at the free ends of their legs with inturned continuous hooks 3. -These rails or tracks 1 and Qiare adapted for lengthwise parallelsecurement by screws or the like 4,v as i115 dicated by dotted lines in Figure 1, to meet the conditions ofdifferent installations, either upon the front faces of the opposite jambs, as in Figure 2', or uponthe opposite inside faces of the frame, as in Figure 1. Suitably mounted for rotary movement at the upper end, and partly within the channel, of track 1, is a two-groove pulley 5, and mounted for rotary movement at the lower end of track 2, is a similar two-groove pulley G. Similarly mounted for rotary movement at the upper end of track 2, is a three groove pulley 7. And it may be here stated that the pulleys 5, 6, and- 7 are suitably mounted within tracks 1 and 2 either with their grooves disposed parallel with the sides of the tracks, as illustrated in Figures 1 and 5, to facilitate the installation shown in Figure 1, or with their grooves at right angles to the sides of the tracks, as illustrated in Figures 7 and 8, to facilitate the installation shown in Figure 2.

8 and 9.indicate runners which are disposed for free movement lengthwise, and within the channels, of the tracks 1 and 2 the runners 8, 9 being substantially of channel section and provided with hooks or the like 10 adapted for retaining co-operation with the hooks 3 of the tracks. The two runners 8, 9 are substantially similar in form and construction, the one runner 8, however, having a bearing 11 for the rotating journal 12 of a shade-roller 13 and the other runner 9 having a non-circular slot 14 for the spring-controlling support 15 of the shaderoller. The bearing 11 and slot 14: so formed and provided in the runners 8, 9 form direct supports for the shade-rollers for the installation shown in Figure 1. For the support of shades for the installation shown in Figure 2, each of said runners is provided at its ends with hooks or flanges 16 and an intermediate bolt or screw hole 17 whereby auxiliary shade-brackets 1818 may be conveniently mounted upon and secured to the runners, as best shown in Figure 6.

Extending over and around each of the pulleys 6 and 7 of track 2 and attached at its opposite ends in eyes 19-19 provided at the upper and lower ends of the runner 9 of track 2, as illustrated in Figure 3 and diagrammatically in Figure 11, is a taut so-called tension cord 20.

Fastened at one end, as at 21, to the lower end of runner 9 and extending under and around the pulley 6, then up and over pulley 7 to and around pulley 5, and fastened at its opposite end, as at 22, to the upper end of the runner 8 of track 1, as diagrammatically shown in Figure 9, is a cord 23, and fastened at one end, as at 24:, to the lower end of, and loosely suspended within track 1 by, the runner 8, is a cord 25 forming an extension of cord 23 and constituting with cord 23 a socalled pull-down cord.

F astened at one end, as at 26, to the upper end of runner 9 and then extending up and over pulley 7 to and around pulley 5 and depending loosely from pulley 5 within track 1, is a third cord 27 constituting the socalled pull-up cord.

Obviously, when the pull-down cord 25 is pulled downwardly, the runner 8 will be directly moved downwardly by the cord 25 and the runner 9 will be siinulta-neosuly and equally pulled downwardly by the cord 23. Obviously, further, when the pull up cord 27 is pulled downwardly, the runner 9 will be directly moved upwardly by the cord without effect through cord 27 upon the runner 8; by reason, however, of the cord 23 being attached to both runners 8 and 9, as described, the runner 8 will likewise be equally moved upwardly with the runner 9, the taut tension-cord 20 functioning, by a so-called braking action upon the pulleys 6 and 7, to maintain the runners 8 and 9 in their adjusted or shifted positions.

Thus in an etlicient, simple manner and by means of two cords disposed at the same'side of the window, the supported shade-roller and its carried shade may be conveniently shifted or adjusted upon and relatively to the window to an I selected or desired lo cation.

It is to be understood that various, changes in the form, construction, arrangement, and combination of the several parts of the shade fixture may be made and substituted for those herein shown and described without departing from the nature and principle of the invention.

Having thus described said invention,

what is claimed and desired to be secured by Letters Patent is:

In a window-shade fixture, in combination, a pair of tracks adapted for secure ment in parallel disposition upon opposite sides of a window,shade-supporting runners disposed for movement longitudinally of and upon the tracks, and means for shifting the runners in unison upwardly and downwardly upon the tracks to selectively locate the supported shade relatively to the window, said means comprising a series of three pulleys mounted for rotation in spaced relation upon said tracks, a first cord having engagement with both said runners and reeved about all three said pulleys, and a second cord having engagement with one only of said runners and reeved about two only of said pulleys, both said cords having free ends loosely depending at one and the same side of the window.
